But they’re also giving another three winners an all-expenses paid trip for four to one of the following runDisney events: The Twilight Zone Tower of Terror 10-Miler Weekend, Disney Wine & Dine Half Marathon Weekend, Walt Disney World Marathon Weekend presented by Cigna, or Disney’s Princess Half Marathon Weekend.

The Enchanted Glass Sneaker | Happily Ever Excellent Sweepstakes runs now through August 31. It’s a digital scavenger hunt where just one person will be able to find the sneakers and add them to their cart for a perfect fit. But everyone can enter the trip giveaway.

Here’s how it works:

1) Visit the sweepstakes page at Zappos.com. If you find the glass sneakers there, try adding them to your cart. Zappos will let you know whether or not they are the perfect fit. Like Cinderella’s glass slippers, they’ll only fit one runner.

If you don’t find the glass sneakers, you’ll see a page that looks like this:

Fear not. If you follow Zappos on Facebook, Instagram, and Twitter, they’ll announce when the sneakers will magically appear on the site so you can virtually try them on for size.

Enter every day for your chance to win. Zappos will announce winners every week on August 16, August 23 and August 30.

Good luck and may you run happily ever excellent!

Disney sometimes provides me with complimentary race entry, hotel, park tickets, and some meals for runDisney events. Zappos and New Balance have not compensated me in any way. I just think all my readers who are runDisney fans might want to know about this!

Notes From A Nerd

I’m not the fastest runner and I’m not the slowest, but I am a running nerd. A journalist by trade, I love to research, read, learn and cogitate. So stick with me. Like all good nerds, I’ll do the homework and share it. But the running is up to you!
